Browning lamb chunks in a pan and then place in dish in fan oven at 180C for 30-40 mins - is that sufficient?

This kind of lamb chunk size:
www.sainsburys.co.uk/shop/ProductDisplay?storeId=10151&productId=1219748&urlRequestType=Base&langId=44&catalogId=10123

Is it just a case of heating a few teaspoons of oil in a pan, ensuring all sides are browned (i.e. leaving inner part uncooked) and then putting it in a casserole dish for 40 mins with other ingredients (5 min cooked rice etc.) at 180C fan oven to fully cook through.

Will that work or will I be left with undercooked/overcooked lamb and/or rice?

Thanks

I'd do it for at least an hour. It would probably be cooked at 40 minutes, but a bit chewy, maybe.

Agree with at least an hour and check the water level

What else are you adding? Veg? What liquid?
